rats., Onl J Vet Res., 23 (3):206-213, 2019.
Groups of 6 adult Wistar rats were gavaged 5, 10, 20 and 40 mg/kg daily zinc oxide
nanoparticles (ZnNano) daily for 56 days. By day 56, rats were
anaesthetized for comet assay of sperm cells, and testes homogenized for malondialdehyde (MDA) and glutathione peroxidase (GPX).
Compared with water controls we found dose dependent rises (P<0.05) in MDA
(35-116%) and declines (22-60%) in glutathione peroxidase in
testis tissue. In those without comets, decreased ~23% in rats given 20-40mg/kg
zinc nanoparticles and in those with high number of comets increased twofold
~220%. In rats given >10mg/kg comet lengths increased ~45-168%, tail
lengths about ten-fold, DNA in tail about 5000 fold, and tail and olive moments
about 3000 fold. We found no effect on head DNA. Our findings suggest that doses greater than
5mg/kg zinc nanoparticles given chronically (56 Days or more may adversely affect testes of rats.
